1' '0 all whom, it may concern Be it known that 1, WILLIAM C. Lane, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Mold- Making Machines; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in mold-making machines, and pertains more especially to a mold-making machine comprising a table, a movable holder or carrier for a pattern-plate, a pattern-plate borne by said carrier, and a movable head for covcring the molding sand supplied to the up-v per flask-section of a mold, the aforesaid table forming a support for a mold-bottom which has the contour and dimensions required to'render it capable of entering and moving endwise of the lower flask-section of said mold and to extend externally of said flask-section downwardly from the body of molding sand supplied to said flask-section, the aforesaid carrier being arranged to more the pattern-plate into a position in which,

the patternplate covers the lower flask-seetion when. the latter is arranged right-end upsubstantially horizontally over the aforesaid table. the aforesaid head having the contour and dimensions required to render it capable of entering the upper flask-section upon being actuated into position covering the moldingsand supplied to said upper flaslcseeti-n, and said head in said position, the pattern-plate in its aforesaid position and the aforesaid table being capable of relative readjustment to reduce the distance between the table and the pattern'plate and between the pattern-plate and said head.

This invention pertains more especially to a machine inwliiirh both the drag and the rope ot' the mold are formed and in which is employed a doublet'aced pattern-plate borne by a holder or carrier which is oscillatoril supported and arranged. to swing in a vertical plane and Min;- arranged over and spar-ed from the aforesaid table when it has been swung into a substantially horizontal position at one side ot the axis of said carrier and being arranged to receive the lowerflaslesoriion l()\\"3l'('fl l-ll]) when it has been s HHQ into a su stantially horiz ntal position at thesaid flaslosection,

opposite side oi said axis i line 3 to be there supplied from above with molding sand and the aforesaid mold-bottom, so that said flask section and said mold-bottom, upon supplying said flask-section with molding sand and applying said mold-bottom to can be swung with the pattern-plate into position over the aforesaid table on which said'mold-bottom is then or ranged to rest and so that the pattern-plate,

upon the delivery of said flask-section rightend-up over said table, not only rests on said flasl section but is in position ,to receive the upper flask-section which upon being there supplied with molding sand is adapted to receive the aforesaid head which is actuated into position over the sand supplied to said upper flask-section whereupon said head, the pattern-plate and the aforesaid mold-bot tom-bearing table are relatively readjusted to reduce the distance between the mold-bottom and the pattern-plate and between the pattern-plate and said head and thereby efiect a compression of the sand-bodies in both fiaslcsections and simultaneously com plete the cope and the drag of the mold.

The primary object of this invention is to greatly facilitate the formation of a com plete mold consisting of a cope and a drag eomprising the upper 'fiasksection'and the lower flask-section respectively. i

Another object is to compress the body of molding sandisupplied to said lower flasksection and the body of molding sand supplied to said upper flask-section during one and the same relative readjustment of the aforesaid head, pattern-plate and table.

Another object is to relatively arrange the movable members of the machine to insure convenience and facility in the operation of the machine. i

Another object is to provide a construction permitting non-uniformit T in the depth of pattern-plates and flask-sections employed in making different molds.

With these objects in view, and to the end of attaining other advantages hereinafter appearing, this invention consists in certain features of construction, and combinations and arrangementof parts hereinafter de scribed. pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure l is a side elevation of a mold-makinmmachine embodying my iurcntion. Fig. 2 is a top plan relativo Io.l*ig:. l. Fig. 3 is a veriirul section on f), '1. looking in llw dire tion inmolding sand. Fig. 9 is ig. 8, but in Fig. 9 the dicated by the arrow. Fig. 4 is a vertical section on line M, Fig. 2. Fig. 5 is a horizontal section, in detail, on 111166- 5, Fig. 4:- Fig. 6 shows the upper portion of Fig. i and furthermore illustrates the hereinbefore mentioned lower flask-section mounted lower-end up on the pattern-plate shows the upper and filled with molding sand. Fig. 7 is a view corresponding with Fig. 6, except-that Fig. 7 shows the body of molding sand in the lower flask-section slightly compressed by a mold-bottom mounted on said body and illustrates means employed for holding said in compressing the body of molding sand in the upper flask-section is shown in position covering saidbody after slightly compressing said body. Fig. 9 also illustrates means employed for preventing upward movement of said head in the sand covering' position of the head and illustrates a par tial movement of certain seat-forming members instrumental in supporting the. upper flask-section independently of the patternplate when required. Fig. 10 is a view similar to Fig. 9, but Fig. 10 shows said head,

the pattern-plate and the hereinbefore men- 'ti'oned table relatively readjusted to reduce the distance between the mold-bottom and the pat'tern-plate and between the patternplate and said head, and Fig. 10 also illustrates the completion of the drag and the cope of-the mold and shows the aforesaid seat-forming members for the upper flasksection as having moved into position under projecting members formed on and externally of said flask-section. Fig. 11 is a side showing the view, largely in vertical section, upper flask-section, and consequently the cope, supported by said seat-forming mem bers for said flask-section, and illustrates the pattern-plate as lowered independently of the cope and the drag as lowered independently of the pattern-plate. Fig. 12 is a view, largely in vertical section, showing the pattern-plate held to the cope while the drag is lowered by gravity. Fig. 13 is a vertical section on 1ine 1313, Fig. 10, looking in- Wardly. Fig. 14. is a horizontal section, in detail, on line l i-14, Fig. 3. Fig. 15is a vertical section, in detail, on line 15-45, Fig. 4., looking outwardly. 1'6 is a verrier t) ereat tical section, in detail, on line 16-46, Fig. 15. Fig. 17 is a vertical section, in detail, on line 17-17, Fig. 7 looking in the direction indicated by the arrow. Fig. 18 is a vertical section, in looking in the direction indicated by the arrow. Fig. 19 is a vertical'section, in detail, on line 19 19, Fig. 2. Fig. 20 is a section, in detail, on line 20-20, Fig. 8.

Portions are broken away in the drawings to reduce their size and to more clearly show certain features of construction.

Referring to the drawings, A indicates the supporting framework of the machine, which framework is shown mounted on wheels at to render the machine capable of being wheeled from one place to another.

13 indicates a double-faced pattern-plate which (see Figs. 2, 4, 6, 7 11 and 12) is re movably secured, by means of screws Z, to a holder or carrier C. The carrier C has two spaced parallel arms 21 which are rotatably mounted on a pivotal rod 22 arranged centrally between the ends and substantially horizontally and transversely of the framedetail, on line 18-.18, Fig. 7,"

work A. The rod 22 pivots the arms 21 to normally upwardly shiftable posts or menihers 23 which are connected together by said rod and loosely embraced (see Fig. ,3) by vertically arranged barrels or tubular members 24 arranged to guide said posts and integral or rigid with the framework A. Each 0st or rod-supporting member 23 rests at its lower end upon a block or seat-forming member 25 which is arranged within the lower endvportion of the guiding member 2% for said post and is provided with a laterally projecting stud 26 which extends through a slot 27 formed in one side and ex tending :up and down said post-guiding member, and a nut 28 is screwed onto said stud externally of said post-guidin member and has its inner end (see also Fig; 14) overlapping the exterior of said post-guiding member. Obviously therefore upon loosening the nuts 28 the seat-forming members 25 are rendered free to be readjusted Vertically, and said seat-forming members are secured in the desired adjustment by tightening said nuts. It will be observed therefore that the seat-forming members 25 are adjustable vertically, and consequently the support for the pattern-plate carrier G, which support consists of the rod 22, is elevated'or' lowered according as the posts or rod-supporting members 23 are elevated or lowered; by the required readjustment vertically of the seat-forming members 25.

The rod 22 and connected carrier C are 0011-.

sequently vertically adjustable, being elevated or lowered according as the seat-formelevate or lower:them, but the posts or rodsupporting members 23 and connected carall times freetoshift vertically upwardly. The vertical 'adiustability and hcreinl'uefore ClQSCIIbBCl application of the carrier are features embodied in my present invention.

By the construction hereinbefore described it will. be observed that the, carrier C is os'cillatorily supported and arranged to swing in a vertical plane, and obviously the pattern-plate B lies in a substantially horizontal position at one side of the axis of said carrier, as shown in Figs. 1, 2, 3, t and (S, to receive the lower flask-section l) lower-nd-t1p to be there supplied from above withmolding sand (Z and a mold bottom E having the contour and dimensions r quired to render it capable of covering said sand and moving endwise of said flasksection, or isarranged, as shown .in Figs. 8 and 9, in a substantially horizontal position over and spaced from a. table G arranged at the oppositesidc of said axis with said mold-bottom resting on the table, according as the pattern-plate has been swung by the carrier C the extent required in the one or the other direction.

The pattern-plate, when it is arranged in position to receive the lower flask-section. preparatory to supplying n'iolding sand to said flask-section, rests and is consequently supported at its outer or free end '(see Figs. 1. 2 and 4) on two sea't-foru'iing members spaced longitudinally of the aids of the carrier C. Each seat-forming member 30 (see l'ij .515 and 16 is )ivotcd substantially horizontally, at 31. to a bracket 3;

and has its axis substantially parallel with the axis of the'rarrier C, Each seatddrn'iing' member 30 is arranged therefore to swing from and toward the of the pat tern-platc-carrier and has an inwardly pro-- iccting arm Iii-3 which has a lug 2d resting on said bracket in the inner position ot'said seat-forming iucmb and roi'iperatinawith said bra ket in forming a stop for limiting the movementof said seat-forming member during the inward swinging of said seatforming member from its outwardly swing or outer position shown in dotted lines. Figs. 7 and lit into its inwardly swungor inner position shown in l ig's. 4, 3 and 17; and in solid lines. Figs. 7 and 16. Each scatformiugmember 30 is also provided with :1 lug which during the outward swinging;- oi" said seat forming men'iber from the position shown in Fig. Al and in solid lines Fig. 1-; into. the position shown in dotted lin -s Figs, 'T and it; comes into. onrag'enieut. as shown in) Fig, 16, with a stoptoruiing surfacc 3.) of the bracket :52 supporting" said s at-formiug member and cooperates with sfiid siggrfz'u-e'in forming a; stop for limiting the zl-i vcment of said seat forming member during the outward swin ing of said seatdorming member. Each of ckct 32 (sec- Fi-ghl) has-adepending vertica lly arranged stem 36 extending into and adios-tablet endwise of a correspondingly arranged sopketforming member 37 with which the framework A is provided, which stem is secured in the desired vertical adjustment to said socket-forming member by a suitably applied set-screw It will be observed therefore that the brackets 32, and consequently the seat-forming members 30, are adjustable vertically, and I would here remark that the vertical adjustability of said. seat-forming members and the herein before described application of said seat forming members constitute a portion of my present invention.

By the construction scribed it will be observed hereinbefore dcthat my nnproved machine comprises a table G arranged atone side of but below the tern-plate-carrier C and has means arranged at the opposite side of said and comprising the seat-formingmembers 30 for axis of the pat supporting the pattern-plate at its free end when said pattern-plate is in position to receive the lower flask-section D of a mold, and Fig. 6 shows said flask-section mounted lower-end-up on said pattern-plate and filled with molding sand (Z, and. Fig, 7 shows the hereinbetore mentioned mold-bottom E not only placed in position downside-up over the body of sand d but depressed somewhat into said flask-section to prevent dis placement of said mold-bottom edgewisc. Hence Fig. 7 shows said mold-bottom having somewhat entered said fiaslescction l) and slightly C(JlllllltSSQt'l the body of "molding sand in said flask-section. When said mold-bottom has been applied. as shown in F T. the mold-bottom. the moldbottom-surrounding sandwontaiuing ashsection I) and the pattern-plate are held to-- gather in any approved manner to tacilitate swinging of the ]l tl'tt01ll-])lui. and connected fiaslnsection and mold-bottom toneither to and over the table G. and said i'nold-bottom rests on said table upon swinging the patterrnplate and connected fla section and mold-bottom to and over said table. as shown in Fig. 8. Fig. Sdlicre'furc shows said mold-bottom right-side up and resting on the tablet}; which is movable vertically as will hereinafter appear. Said mold-bottom is th ck enough to extend downwardly from the body of molding sand in the fiaslcsection l2 far enough beyond the lower extremity or ext section to space said fiaslcsrction from the table (l. as shown in Fig, 8. the extent required to permit the moid-l'mttom. during the elevation of said table as will herrinat'ter appear. to outer said this c-sc iiou l'ar enough to'cli cctthercquisite compre sion f said body of molding-sand which is covered by the pattern-plate when the pattern-plat rests on said tiaslcsection as shown in b.

crnally of said llash-' Means for preventing displacement of the mold-bottom E from the body of molding sand in the fiasksection D during the swinging of said flask-section from the position shown in Fig. .7 into position over the 4 table G, [as shown in Fig. 8, are provided,

' to saidflask-section, as shown in Fi 'fillingsaid flask-section with molding sand,

the desired adjustment.

and preferably consist of a'frame which is rotatably mounted on the rod 22 and (see Figs. 7 9, 1( and 18) comprises two rods 40 which form the central portion of said frame and in the operative position of -said frame extend through recesses 6 formed in the under or outer side of said mold-bottom, and said frame preparatory and during the filling of the lower flask-section with molding sand, when the pattern-plate is in position resting on the seat-formin 'members 30, as shown in Figs. 1, 4 and 6, is arranged over the table G, as shown in Figs. 1 and 2, and has its members 40 resting on a crossbar or member 41 of theframework A, (see also Figs. 4, 6, .11 and 12) but said frame, upon the application of the mold-bottom E 7, after is swung from the position shown in Figs. 1 and 2, into the position shown in Fig. 7 and in said last-mentioned position has the rods "40 thereof engaging the bottoms of the recesses e which extend across said bottom,- that is, between the axis of the pattern-plate- -carrier C and the free'end of the patternplate,andconsequently said Yrods extend, in the posit-ion shown in Fig. 7 between said axis and said end of the pattern-plate, but

are spaced from said axis. Each ,rod 40 (see Figs. 7 and 17) is provided at its end adjacent the pattern-plate carrier C with an arm 42' which projects toward and is ar-j ranged radially relative to the axis of said carrier and'extends into and is adjustable endwise of a socket-forming member 43 which is rotatably mounted on the rod 22 and provided with a suitably applied setscrew 44 employed in securing said arm in Each rod 4-0 (see Figs. 7 8 and 18) is provided at its opposite end with an arm 45 which is substantially parallel with and arranged opposite the arm 42 of said rod and projects into a socketforming member &6 formed on a cross-rod 47 which is employed in connecting the rods 4-0 together at their outer ends, and the arms 45 of the rods 40 are adjustable endwise of the socket-forming members 46 and secured in the desired adjustment by suitably applied set-screws 4-8. Itwill be observed therefore that the rods 40 or central and mold bottom-engageable portion of said frame are adjtstable at theiriuner ends from and toward the rod 22 to render said frame applicable to flask-sections which are -connected lower fi on the rod 47-eentrally between the ends ofsaid rod and provided with a shoulder h which in the operative position of the latch when the frame has been applied to the mold-bottom E, as shown inFig. 7, over-' laps the downwardly facing surface of the tern-plate and thereby holds the patternplate and the flask-section D togetherand causes the rods 40 to hold the mold-bottom in contact with the body of molding sand in said flask-section. It will be observed therefore that the cross-rod 47 is adjustable to render the latch H capable of being aceur'ately positioned relative to the patternplate when the flaslesection D is in position on the pattern-plate in the position of the pattern-plate shown in Fig. 7 and that said adjustability of the said cross-rod and connected latch accommodates the applicationof the latch to the pattern-plate during a readjustment of the rods 40 or central portion of said frame from or toward the rod 22 as required for a deeper or shallower flask-section than shown in Fig. 7. I would here remark that the adjustabiliiy of the rods 40 frame toward and from the axis of said frame and the adjustability of the latch H of said frame in accordance with the adjustability. of said rods or moldbo-ttom-engageable portion of said frame -constitute features of my present invention. The importance of the vertical adjustability of the rod or support 22 for the patternplate-carrier C will be obvious in view of the fact that the pattern-plate, when it has been swung into position over the table G, sh 'uld lie substantially horizontally, and that he use of a lower flask-section deeper or shallower thanshowuin Fig. 8 necessitates such a readjustment vertically of the seat-forming members 25 as will insure a substantial horizontality of the pattern-plate in its position shown in Fig. 8 and space the pattern-plate in said position from the table G the extent required to accommodate the location between the table and the pattern-plate of the sand-body in said flask-section and the mold-bottom E. The pattern-plate, upon swiuging'it and the as (-SQCilOli and mold-boitom to and over the table G, as shown in Fig.8, is in position for the r eption of the upper fluslesection I of the mold, and said upper flask-section upon being mounted, in line vertically with the lower flask-section 1). on the pattern-plate in aid position projecting outer or free end 49 of the patof.the pattern-plate. is tilled with molding sand J. as shown in Fig. 8. whereupon a head K. borne by .a-holder or carrier L and employed ioeover the body of molding sand supplied to the upper flask-section l and I struniental in compressing said sand, is zutuatcd into position .over said body and slightly. depressed to 'cause it to somewl'iut enter said upper flasksectin and thereby somewhat compress said sand. It will be observed that the pattern-plate-carrier C and connected pattern-plate are capable of being elevated independently of the headcarrier L and connected head in the position flask-section as will hereinafter appear.

The head K (see Figs. 4-, G, 7, 10, 11 and 12) is shown-removably secured, by means of screws 51, to the carrier L which oscih latorily supported and (see Figs. 2 and has two substantially parallel spaced arms 52arranged adjacent the ends of the rod 22, and each arm 52 is pivoted substantially horizontally, as at Z, to a bracket supported from the framework A. The arms 52 have thei axes coincident and substain'ially parallel with the axis of the pattern-platecarrier C. It. will be observed therefore that the head-carrier L has its axis arranged in proximity to and substantially parallel .with the axis of the patternplate-carrier C and is arranged to swing in a vertical plane. Preferably each bracket 53, as shown in Fig. 3, has a laterally and outwardly facing serrated surface 54; engaging a laterally and inwardly facing correspondingly serrated surface with which the adjacent portion of the framework A is provided, and a bolt 56, which is arranged substantially horizontally and parallel with the axis of the carrier L, extends througl'i a lateral slot 57 formed in said portion of said framework and through said bracket and has its head overlapping the inner side of said bracket. A nut 58 is screwed onto said bolt at the outer side of aid portion of the framework. and a washer 59 interposed between the framework and said not. Uponlooscning the nuts 58 the brackets are rendered free to be readjusted vertically, and said brackets are secured in the desired adjustment by tightening .id nuts. Obviously therefore the brackets 53', or support: for the carrier L, are adjustable vertically. and consequently the carrier L elevated or lowered according as said brackets are elevated or lowered by the requit-ed. adjustment vertically of the said brackets.

The head if has the contour and dimension required to render it capable of enterthe upper flask-section I at the upper end of said llaslesection and permitting said tlasl-z-smtion to be elevated independently of said head. but said h nd is in position covusing the body of molding sand supplied to said flask-section when the pattern-pla e is in misition ov r the lower flaslesectionll arranged between the pattern-phte and the table G as shown in Fig. 9, or arranged under the pattern-plate in a substantially horizontal position when the Pitt lit n-plate is in position resting on the seat-.tmlnin'g members 30, as shown in Figs. l, 4. 6 and 7, according as said head has been swung the extent required in the one or the other rlirec ion.

It will. be observed thatthe head-carrier 11, when the head K in position under the pattermplate in the position of the patternplate shown in Figs. 1, l, 6 and. '4', rests upon the arms 33 of the seat-forming members and is therefore indirectly supported from the brackets 32 in said position of the pattern-plate. It will be observed also that said seat-forming members 30 project over the head K in said position of the pattern plate and consequently projee into the sweep of said head so that said head during its actuation from the position shown in Figs. 1,2. 8, st, 6 and 7 into the position shown in l ig. 9 comes into engagement with and swings or throws said seat-forming members out 'ardly into the position shown in dotted lines Fig 7 and 1G, and that: in said position of said seat-forming members the arms 33 of said seat-foriming members project into the sweep of the head-carrier l'i so that said carrier during the actuation of the head K from the position shown in Fig. 9 into the position shown in liigs. l, 2, l, 4. t3 and 7 comes into engagement with said arms and thereupon swings the seat-forming n'ienibers. 3O inwardly into the position shown in Figs. 1, 2. t, t) and 15 and in solid lines Figs. and 16.

A not unimportant feature of my present invention consists in the provision of means for preventing sagging of the central portion of the pattern-plate when the patternplate is .in position resting; at its outer or free end on the seat-forn'iing members 30, and the means shown for preventing said sagging of said portion of the pattern-plate in said position of the pattern-plate Figs. 1. t an dlil') comprise two pins or members M movable with and shiftable endwise independently of the head K. The pins M e ro tend through holes 61 in the central portion I of the head K and are spaced longitudinally of the axis of the carrier L. Each pin M has a head m countersunk within the sand-compressii'ighead K and arranged flush with and participating in forming the face ofsa d sand-compressing head when the latter is in the position shown in Figs. 9 and 13. The pins M are arranged substantially perpendicularly to the head K and extend beyond the backof said head. Nuts 62 are screwed onto the pins M opposite and spaced from the back of the head K, and spiral springs 63 are coiled around said pins and confined. be tween said nuts and said back and act to re v tain said pins in the position in which their heads m are flush with the face of the head K. The piiis M, when the head K is in posi- I tion under the pattern-plate and when the pattern-plate rests on the seatforming member 30, as shown in Figs. 3 and 4, above said head, rest at their lower ends on brackets 64 supported from a cross-bar 65 of the framework A. Each bracket 64 is rovided (see Figs. 3, 4; and 5) with a vertically arranged slot 66 extending laterally therethrough, as shown in Figs. 4 and 5, and a bolt 67, as shown in Figs. 4 and 5, has its shank extending laterally through said cross-bar and beyond the'bracket-facing side of the cross-bar and through the slot 66 in saidbracket and has its head at the opposite side of the cross-bar and a. nut 68 is screwed on the free end of said shank, and a washer 69 isinterposed between said nut and said bracket. pon loosenin the'nuts 68 the brackets 64 are rendered gree to be readjusted vertically, and said brackets are secured in the desired adjustment by tightening said nuts. It will be observed that the brackets 64 have such arrangement relative to the pins M of the head K that said pins during the actuation of said head into the position shown in Figs. 3 and 4 come into engagement with tliebrackets 64 and are elevated by said brackets against the action of the springs 63 and far enough to cause the heads of said pins to make contact "with and brace or support the central portion of the pattern-plate when the pattern-plate is in position resting on the seat-forming members 30.

By the construction hereinbefore described it will be observed that the vertical adjustability of the brackets 53 or support for the head-carrier L renders said carrier, and consequently the head K, adjustable to accommodate the use of flask-sections which are deeper or shallower than the flask-sections illustrated, and that said head, when it is in position under the pattern-plate in the position of the pattern-plate shown in Figs. 1, 2, 3, 4, 6 and 7, is out of the way but accommodates the requisite arrangement of the hereinbefore described means employed for preventing sagging of the central portion of the patternrplate, and "I would here remark that said head and its application and arrangement relative to the table G and the application of the pattern-plate constitute invaluable features of my present invention.

By the construction hereinbefore described it will be observed that my improved mold-making machine not onlycomprises a table arranged at one side of and-below the axis of the pattern-plate-carrier which is arranged to swing in a vertical plane, that during the operation of the machine the pattern-plate and connected lower flask-section friction between the sand-body and mold-bottom are swung'to and over said table, and that said mold-bottom rests on said table when the pattern-plate and connected lower flask-section and mold-bottom have been swung to and over said table, as

chine also comprises an oscillatorily sup- 7% shown in Fig. 8, but that my improved maw ported holder or carrier bearing ahead K i pattern-plate is in position at the. opposite side of said axis for receiving thelower flask-section, as shown in Fig. 6, that said head during the operation of the ma-' chine is arranged to be' swung into position over the upper flask-section, as shown in F 9, for participation in the compression" of the sand-body in the-upper flask-section mounted on the pattern-slate npon swing ing the pattern-plate an connected section and'inold-bottom to and'over aforesaid table, and'lwould here were that upon swinging said head into its ass mentioned osition the table is elevated toeffect the e ovation of the mold-bottom, as 1 *shown in Figs. 10 and 13, but before the elevation of said table the latch H is thrown into an inoperative position in which the latch is out of engagement with the atternplate, as shown in Fig. 10. It wil beobserved that notwithstanding the movability of the mold-bottom upwardly independently of the lower flask-section there is enough in said flask-section and said flask-section to effect an upward movement of said flask-section, the pattern-plate on said flask-section and the upper flask-section independently of the head K- and thereby'reduce the distance between said head and the pattern-plate, but I the mold-bottom. being movable upwardly independently of the pattern-plate, moves farther during the elevation of the table G than ,the lower flask-section, pattern-plate and upper flask-section so as to reduce the distance between the pattern-plate and the mold-bottom.

Means for preventing upward movement of the head K during the elevation of the pattern-plate and upper flask-section are provided and comprise'two latches P which are pivoted by the substantially horizontallyarranged removable pins '71 to the headcarrier Lat the free end of said carrier and have their axes substantially parallel with the axis of said carrier. arranged therefore to swing in a vertical plane and, when the head K is in a position below the pattern-plate in the position of the pattern-plate shown in Figs. 1. 2, 4, 6 and- Each latch P is attached one end of a counterhalai'ice spiral 19 to prevent said latch from dropping downwardly into a position in which it might be in the way. The latches P, upon the actuation of the head K into the position shown in Figs. 0, 10, 3.1., and 12, are arranged in a position in which they project downwardly from the carrier, and. each latch l is provided at its free end with a shoulder ill which faces upwardly in the last-mentioned position of the latch and overlaps a. downwardly facing surface 7% formed on the framework A. so as to cooperate with said framework inpreventing upward displacement of said head inv the posi tion of the head shown in Fi 9 during the upward movement of the pattern-plate and upper flask-section independently of said head. It will he observed therefore that during the elevation of the table G the mold-bottom, the patternplate and the head K are relatively readjusted as required to reduce the distance between the table and the pattern-plate and between the patterirplate and said head so as to eitcct a compression of the sand-bodies in both flasksections.

As shown in Fig. 19, the pin '71 employed in pivoting a latch P to the carrier L engages the central hole of three holes 75 formed in and spacedlongitudinally of said latch, and hence by removing said pin from said hole and pi voting said latch to said carrier at one of the other of said holes, said latch is readjusted longitudinally.

To each arm 52 of the h adr.-ari.'ier L is spring Q prefe ably removahly hy a suitably applied set-screw 93. as shown in Figs. 1 and 5). and said spring is attached at its other end to the framework A in any approved nianncr. The head 1( is preferably arranged exact y horizontally when said head has somewhat entered the upper liashsection. as shown in Fig. 9. and the springs Q act to retain said head in the horizontal position shown in Fig. il. To facilitate movement of the latches 1 into their operative position in which the shoulder 73 of each latch l" overl ps th adjacent surface H t f the. franwwork A the head K is depressed somewhat farther into the upper fins-lo section than shown in Fig. l whereupon the positioning of said head horizontally by the springs Q, upon such depression ot the head insures contact. helwccn the shoulder 73 of each latch l and the adjacent surface T-l oi? the framework A. as showu'in Fig. 5). hut. of course leaves some space To l)tl' \'\"lll. said head and the sand-body J which is compressed somewhat during said depression ot. said head.

The table (l (see Figs. 1. 2. S. .3. 10,11 and 13, is n'ovideil at the under side of its ceir tral portion with two laterallyv spaced depending vertically arranged stems 77 which which extend from side to side of the ma'- chine and are supported from the traniewort A, and each shaft 80 is provided centrally between its ends with an upwardly projecting arm 81. The arms 81 01. the two shafts 80 are operatively connected together by a suitaiily applied link 82 which is arranged horizontally and at a. right angle to said shafts and extends between the eylinoers 78. Each shaft 80 is provided with two arms 83 which project laterally of the shaft and are arranged between the arm 81 of said shaft and opposite endsmespcctively of the shaft and substantially-ata right angle to said arm 81. The arms 83 of the shafts 80 project in the same direction and are operatively connected by suitably applied upright links 84 with the table G. Each shaft. is provided with the lower section 8.; of a collapsible lever for operating said shaft. The operating levers of the shafts 80- are arranged at opposite sides respectively of the ina li' 10, 2714 shown in Figs. 1, Q, S and 9. and each lever has an upper handle-forming section 86 which is pivoted substantially horizontally, at 87. to the lower section ot' the leve and has its axis suhslantially parallel with the shafts 80. The upper section Sh of each lever normally depend roin the upper end of the lower section i of the-lever. as shown in Figs. 1 and 8 and in solid lines in Fig. 9." he lower section S5 of each lever has an upper end face SSPKHIHHHQ' from adjacent the axis of the upper section So of the lever in the direction in which the lever is actuated to elevate the table. and an id upper section of the lever is orovided with a shoulder 89 arrangei'l to abut against said end face upon swineing said upper section of the lever upwardly. as shown in dotted lines in Fig. 9. into its operaiive position preparatory to swinging the lever in the direction required to elevate the table (l. and Figs. 10 and 11-1 illustrating the table as elevatial of; course show the upper section of a lever in its operative position. The machin illustrated is therefore designed more especially tor making large molds audio hiopcratcd by two attcmlanls stationed at op- 1)() ll0 sides respectively of theniachinc.

The upper flash-section and the compre sed sand-hody in said iiaslesection. a. shown in Figs. 10 and 13. form the cope of the mold. The lower i'lask-section and the comm- L sand-body in said flask-section,

tration in this specification, of means for fastening the mold-bottom.- and the lower flask-section together upon the formation 'of the drag, as such fastening means are not involved in my present invention, are not considered necessary.

A not unimportant feature of my present lllYUlltlOn consists in the provision of means instrumental in holding the upper flask-section, and con equently the cope, elevated indcpcndmtly of tl. pattern-plate, as shown in Fig. 1, (lllllllg' the descent of the table G by gra vity iuo its lower-and normal position, and (see. Figs. 1., 2, 8, 9, 10 and 13) the means shown for holding the cope elevated independently of the pattern-plate comprise a pair of seat-formin members R for supporting the upper flash-section ad jaeent the inner end and independently of the pattern-plate upon the formation of the cope, and also a pair of seat-forming members r for supporting said flask-section adjacent the outer or free end and independently of the pattern-plate upon the formation of said cope, The seat-forming mem bers R and r are pivoted substantially horizontally, as at 91, tothe framework A and arranged to swing in a vertical plane, having their axes substantially parallel with the axis of the head-carrier L. The two seat-forming members R and also the two seat-forn'nng members 7 are spaced longituthe pattern-plate is in the position shown in 1 Figs. 8, 9, 10, 1'1 and 13. The seat-forming members R are operatively connected with the seat-forming members 7 by links The links S are attached to the seat-forming members 0' above the fulcrums of said seat-forming members and are attached to the scat-forming members R below the fulcrums of said last-mentioned members. Obiously, therefore, swinging of the seatforming members R in the direction required to move their upper ends toward the seat-forl'ning members 1 will resi'xlt in swinging the last-mentionedmembers in the direction required. to move their upper ends toward the scat-forming members R.

5: Each arm 52 of the carrier L is provided with a resilient member 92 which is shown attached to said arm by the screw 93 employed in attaching the adjacent spring Q to said arm and extends circumferentially of the axis of said carrier from the point of attachment of said resilient member to said arm in the direction in which said carrier is swung in swinging the head K from theposition shown in Figs. 9, 10, 11, 12 and 13 into the position shown in Figs. 1, 2, 3, 4, 6, and'7. liiach resilient member 92, in the position of the head K shown in Figs. 1, 2, 3, 4, 6 and 7 is nearest the axis of'the carrier Lat the point of attachment of the said resilient member to the connected arm 52 and is gradually spaced farther from said axis in thedireetion of the free end of said resilient member, so that said relative to said axis;

The two pairs of seat-forming members .resilient member is arranged eccentrically R and r, in the inoperative position of said spaced from the longitudinal edges of ribs 94. formed on and externally of the upper flask-section and are adapted to be swung toward each other and into contact with said edges of said ribs, as will hereinafter ppear. i

The arrangement of the resilient members 92 of the arms 52 of the head-carrier L is such relative to the seat-forming members It I that said resilient members, during the actuation of the head K from the position shown in Figs. 1. 2, 3. 4, 6 and 7 into the. position shown in Fig. 9, come into engagement with the upper end-portions of said seat-forming men'ibers' and thereupon actuate said scatforming members during said movement of said head against the longitudinal edge of the adjacent rib 94 of the upper flask-section and are placed under tension during said actuation of said seat-forming members, and ig. 9 shows said seat-forming members as having been actuated by the resilient members 92 against said rib, and it will be observed that the relative arrangement of the parts is such that during-the actuation of the seat-forming members R'against said rib, the seat-forming members 1*. as shown in Fig. 9. are actuated into contact with the longitudinal edge of the rib 9-1.- adjacent said last-mentioned seat-forming members. During the elevation. of the upper flask-section by the pattern-plate during the hereinbefore described relative readjustment of the pat- L WASF bring its external ribs or projecting members 94 somewhat above the seat-forming memhers R and 2; as shown in Fig. 10, and as soon as said flask-section has been elevated the extent required to bring said projecting members above said seat-forming members, the resilient. members 92, being under tensionfefl'ect a movement of the seat-formi'ng members R farther in the direction required to cause the upper endsof the last-mentioned seat-forming members to move under the ad jacent rib or projecting member 9st of the upper flask-section, and obviously said -movement of the seat-forming members R results 111 the movement of the seat-forming n'ienibcrs r to bringthe upper ends of the last-mentioned seat-forming members in under the rib or projecting member 94 adjacent the last-mentioned seat-forming members as shown in Fig. 10. Fig. 10 therefore shows the seat-forming members R and r in an operative position. It will be observed that as the upper flask-section during its up ward movement moves far enough to space its ribs or projecting members 94 upwardly from the scat-forming members Band 7*, as shown in Fig. 10, the cope. consisting of the flask-section and the body of compressed sand in said fiask-section, will, upon the completion of thenpwa rd movement of said .tlasksectiom have to descend somewhat to seat. said flaslvsection. and consequently the rope, on said seatforming members, as shown in Figs. 11 and 12 preparatory to the separation of the pattern-plate from the rope and the separation of the drag from the pattern- 'ilatc, as shown in Fig. 11, or preparatory to the separation only of the drag from the pattern-plate as shown in Fig. 19. Upon the completion of the drag and the cope, as shown in Fig. 10, the table is permitted to descend by gravity into its lower and normal positionyshown in Figs. 11 and 12. Fig. 11 illustrates thedrag and the pattern-plate as having lowered by gravity with the table G, but as the mold-bottom, upon the torn'iat'iol'r of the drag, will have moved farther into the lower flask-section than before the compression of tl'resandbodies in the flask-sections during ethe requisite relative rea djustment of the table, pattern-plate and head G, the. drag is obviously spaced from the pattern-plate in the lower and normal position of the table;'as shown in Fig. 11. and of course the pattern-plate in the position shown in Fig. 1.1 is also separatedirom the rope because the latter is supported from the scat-forming members R and r int'lependently of the patterirplate and prevented from descending as far as the pattern plate. scending into the position shown in Fig. l1,' is obviously supported at itsinne'r end from the seat-forming members 25 through the medium of the rod 22 and posts 23, as said "Having withdrawn the drag from the The pattern plate; upon deposts in said position of the pattern-plate rest upon said seat-forming members but to prevent the pattern-plate from descending at its outer or free end after the descent of the pattern-plate at its inner end has been arrested during the descent of the table into its normal and lower position, as shown in Fig. 11, meansi'or supporting the patternplate at its outer or free end independently of the lower flask-section D as soon as the descent of the pattern-plate at its inner end hasbeen arrested are provided (see 1, E2, 8 and 11) and comprise brackets T borne by the seat-forming members r, which bracket's are out of the way in the inoperative position of said' seat-forming members 7', as

' shown in Figs. 1, 2 and S, but are in position next below the portion 49 of the patternplate and form seats for the pattern-plate at the outer or free end of the pattern-plate upon the descent of the pattern-plate into the position shown in Fig. 1.1. It will be observed that each seat-forming member 1 is provided at one side thereof with a bracket T which Figs. 8 and 20) provided with a slot t extending laterally through and upand down said bracket. and a bolt U, as shown in Figs. 8 and 20, has'its shak extending horizontally and laterally through. said seat'forming member and beyond the hracketdacing side of said seat-forming member and through the slot 6 in said bracket andhas its head abutting against the opposite side of said seat-forming member, and a out a is screwed onto the free end of said shank and clamps the bracket to said seat-forming member. Upon loosening the nuts 'u the brackets T are rendered tree to be readjusted to elevate or lower them, and said brackets are'seeured in the desired ad justlnent by tightening said nuts. The descent of the cope from the position shown in Fig. 10 onto the seat-forming members R and r. as shown in Fig. 11, separates the sand-body of the cope from the head K cnough to'permit depression of said headcarrier L t 1e extent required to sutiiciently loosen the latches I at their shoulders 73 relative to the downwardly facing surface 74: of the framework A and thereby render said latches free to be rendered inoperative preparatm'y to swinging the head K from the position shown in Fig. 11 into the position shown in Figs. 1. 3, 4, 6 and 7, and upon said-swinging of said head the cope is retr dercd tree to be removed from the machine.

pat.- tern -plate and tl'ie-pattern-plate from the cope as shown in Fig. 11, the cope, upon swinging the head K from' the position shown in Fig. 11 into the position shown in Figs. 1. 2, 3, 4, 6 and 7, is removed, wher e' upon the pattern-plate is swung from the position shown in Fig. 11 into the position shown in Figs. 1, 2, 3, 4, Gand 7 for the re- Lite) 'l'orinine members ll in their ino ierative psition shown in Figs. 1, 2 and S are arranged out oi' the sweep of said. shoulders on the patterrrplate but have their upper end-portions arranged within said sweep in the opera't-ive position of said seat-forming memhers so that. said shoulders shall during the swinging ot the pattern-plate from the position shown in Fig. it into the position shown in Figs. 1, Q, 3, "l, (3 and 7 come into engagement with the said seat-forming members and etieet the actuation of said seat-torn-ling, rnen'ibeis and the connected seat-torming members r into their inoperative-position.

It will he observed that the bolt U for each bracket; T is spaced from the lower end ofthetslot If in said bra ket, as shown in Figs. 8 and l l, and hence said bracket is not shown in its lowerir'iost position in Fig. 11. Suppose, for instance, that, as shown in dotted lines Fig. 12, the pattern-plate com prised projections for forming cavities in the sand-bodv of the drag, which projee- 'tions have such tl'lll'lOliSlOYlS that the patternplate. it? lowered as far as shown in Fig. 11, could not be swung from the position shown in Fig. llinto the position shown in Figs. 1, 2, 3, 4-. (t and 7 without resulting in mutilation of said sand-body. The importance of the, hereinhefore described adjustability of the brackets T of the seat-forming members r is therefore obvious, and said braekets are readjusted, for a pattern-plate having said projections, as required to elevate said brackets, as shown in Fig-12, far enough to prevent, the pattern-plate from descending or separating at its outer or free end from the cope during the withdrawal of the drag from the INEttQIIIPIUlRlTP during the descent of the table into its lower and normal position.

Fig. 12 shows the pattern-plate and the drag spaced apart far enough to tree the projection 60 (shown in. dotted lines) from the sand-body of the drug, but to adequately space the pattern-plate from the drug from end to end of the patlern- 'ilate, as shown in Fig. 12. it: is also not unimportant to pro vide n'ieans for preventing the separation of the patte n- 'ilate at its inner end from the cope. and means for preventing the descent of the patternp]ate-carrier, when the pat tern-plate is in the position shown in Fig. 12, is therefore provided and (see Figs. 2, 3 and 10) con'iprise a. short rock-shaft V whicharranged substantially horizontally and at a right angle to the rod 22 and eentrally between the post-guiding members Said shaft is supported from the framework A in any 2l]')]')l't)\'(btl manner and provided, with a l ver 11; for oscillating the sliai't and also provided with two arms )6 arrai'iu'tal radially at diametritailly opposite. sides respectively of the shaft. Between the shaft W and ear-h post 253 is arranged a clamping Inen'iber a: which is pivoted horizontally, as at 97, to the adjacent post-guiding members 24 and has its axis parallel with the shaft W, and said elal'nping member is arranged to clamp said post to said pest-guiding member which is slotted, as at 98, to accommodate the location and operation of said clamping member. Said clamping member is operatively connected with a link, y/ which extends from said clamping member toward the shaft W. The links 1 are operatively connected with opposite arms 96 respectively of the shaft-N. The clamping members m are shown in an inoperative position in Fig. 3, but the relative arrangement of the parts is such that said clamping memhers are rendered operative and thereby I caused to clamp the posts 23 to the post guiding members 241 upon oscillating the shaft W in the direction and to the extent required to bring its arms 96 into the position shown in dotted lines. Of course preparatory to rendering the clamping members a operative the set-screws 44 of the frame comprising the rods 4-0 are loosened to permit lowering of said frame independently of the pattern-plate. I would also remark that the upper flask-section is shown beveled, as at 99, at its upper end as and where required to facilitate swinging of the head K from the position shown in Figs-l1 and 12 into the position shown in Figs. 1, 2, 3,4 6and7.
